Transportation: will promote the construction of new channel solution expressway traffic congestion
On August 26, the Beijing Tibetan highway traffic congestion, alleviate traffic just days new phenomenon recur. About congestion, large cargo drivers first mention is that of badaling highway refused to four tons of these vehicles, trucks entering into state highway 110 to all.
But many experts said, it is not the congestion. Transportation planning institute an expert thinks, congestion is the most important reason, as the traffic trunk, northwest Beijing expressway bear much freight pressure, exposed the long and narrow corridor of single mode of transportation.
This research center, the Beijing transportation WenHuiMin deputy chief engineer with regret. WenHuiMin said, the most direct and efficient solution to traffic congestion, is a special railway line up, will originally should not assume by expressway of pressure.
Recently, traffic transportation minister li shenglin on expressway traffic problems, and carry out special investigation to promote the construction of a new channel, build national highway 110 of urban-rural benefit readjustment, as soon ZhangZhuo fixed support in hebei province.
Funnel network
Multiple speed and national highway, forming the fractal DuiJieChu, funnel network traffic, which causes the slow speed of road vehicles for, cause congestion
Many large cargo driver introduction, because many years ago, the serious traffic accident in the second half of 2008, Beijing transportation management department to ensure safety grounds, refused to four tons of trucks entering badaling highway, the traffic is only limited to four lanes improved state highway 110.
Therefore, Dan, big, Beijing on the expressway from hebei zhangjiakou besides freight vehicle to Beijing, first, the new expressway toll, and chong or in Beijing on the state highway 110 domestic and freight traffic again together to form new by 110, northwest provinces and Inner Mongolia freight cars of Beijing only.
So many national highway and docking, forming a funnel shaped, high-speed road traffic network, the more of the slow speed DuiJieChu, and cause the vehicles for high-speed road, caused the traffic congestion.
At the same time, 4 tons of freight diverted, also cause state highway 110 overwhelmed.
2.5 million cars, this is the beginning of design of highway 110 per day, and now, “the big day per is 1.2 million, converted into cars, about five million vehicles. At least 60%.” SheJiLiang beyond
Beijing participated highway WangHuiPing previously ZhiDuiChang deputy team that, with insufficient resources, in the expressway, the officer on the highway, 110 state road, besides vehicles into new state highway 110, is now the important reasons for the road is enormous pressure. But long-term overloaded load flow state highway 110, let loose autobahns appear problems, such as road traffic safety effect.
Therefore, August 23, 110 state road surface with yanqing near the junction of changping began to overhaul. Two construction, every single one lane is reserved for the direction, total duration is 25 days. Section expressway construction that 50 percent lower than the original traffic congestion, the situation worse.
The traffic
In order to cure, Inner Mongolia, hebei, Beijing are introduced. But these measures are not be received desired effect
According to Beijing and hebei congestion in Inner Mongolia, to the Tibetan highway driving order autobahns conduct centralized control, along the toll remote, more limited flow, according to gradually release. Quotas,
In addition, in order to alleviate the pressure, the height of Tibetan traffic on July 15, Inner Mongolia for expressway, implementation of Inner Mongolia, single line control limit in Beijing BaiYan flowers to hide expressway, 5 axis with ji (above), no single truck into its ShuangRi, double, does not conform to the truck traffic conditions shunt state highway 110.
But in June this year, zhang bureau issued notice: zhang of Beijing area, especially a large trucks, cars, all round, strictly highway traffic jiakou, Dan, big, ZhangShi highway. Hebei high-speed command center, and the measures of personnel, mainly because the cause congestion trucks, 2/3 of Inner Mongolia is from the tram.
Beijing JiaoTongWei says 22 points per day to 4:00, in changping district, freight trucks huandao shunt expressway out all the time period, Beijing, national highway 110 old line double improvement, adding a single Beijing Beijing lanes. At the same time, in order to ensure the vehicles, daily badaling tourism 6-15 points, the direction of the expressway traffic freight trucks, prohibited by 110 old line out of Beijing.
But so far, these measures are limiting and can’t receive desired effect.
In yanqing non-proletariat toll, truck drivers, because had said Chou, usually through traffic stood three or four hours, wall station is normal. Each big truck through at least 5 minutes, also need to, if found, still need more overloaded consumption for an hour.
Design of evil?
According to insiders revealed in hebei province, the transportation system design is original jiakou high-speed bidirectional six lanes, but ultimately compression for two-way four lanes. In this view, the relevant company denies
Expressway and zhang jiakou expressway, name of zhangjiakou traffic bureau, according to a report in 2005, the junction of high-speed Beijing has basic in hebei perennial half paralyzed. The most serious traffic, has been blocked from Beijing to zhang ji interface for 130 kilometres west, by blocking traffic 30,000 cars, nearly 10 million people stranded personnel, the longest of 34 days.
Along with the continuous, a kind of congestion on the design of high-speed defects in traffic system, internal circulating.
According to insiders revealed in hebei traffic system, the design of high-speed is planning, but because the two-way six lanes in funds investor huaneng group, the design scheme, will adjust the four-lane highway compression for two-way at once, though hebei bureau for maintaining the original plan, but failed to work.
In this view, hebei huaneng Beijing highway of limited liability company denies, staff said design does not exist, and eventually change of construction also got approval of the government. In reality, the working personnel of congestion does not understand, say nothing. But for sure and design
The Chinese people’s political consultative conference in Beijing that LiaoLiChun expressway traffic congestion and not design flaws, but is man-made.
Human cause wall?
The Chinese people’s political consultative conference, Beijing, hebei LiaoLiChun think a transit vehicles in domestic highway, interception, thus the penalty for for local revenue. But this is disputed by related departments to refute
Hebei east garden, the first toll from here goes the badaling highway, another road linking Beijing is the state highway 110.
The Chinese people’s political consultative conference in Beijing that the LiaoLiChun garden, the FenDao mouth before the toll of expressway, as a whole, is the crux of expressway traffic congestion.
LiaoLiChun said, this FenDao set a single word mouth, due to the release of card, four37-metre cart to difficulty extremely slow traffic. He said, the setting of the throat, expressway, Beijing flat.
LiaoLiChun thinks, this kind of congestion is local, the purpose is to cause a transit vehicles in domestic highway, interception, thus the penalty for for local revenue.
In order to prove the expressway traffic congestion is man-made, instead of design flaws in China, the design LiaoLiChun speed limit traffic. He said, according to the Beijing changping traffic team to provide the data, present the expressway traffic flow, 1.7 million vehicles for peak expressway, and the design flow is 5.5 million vehicles in the extreme. By contrast, China’s RiGaoFeng flow speed for 6 million to 7 million, but never happen, “a large-scale traffic flow for design limit only one-third of the highway, why so serious? Anyway wall is man-made.”
For this, the first highway traffic police were dismissed. Team officials said, in order to guarantee the traffic environment, Beijing territory in practice, and offers section at ease congestion already. This staff said, traffic police could not human, “this set against our job function, the unit must not promise.” This highway traffic police brigade zhangjiakou are confirmed.
The solution
To solve this problem, the most direct and efficient way is to open a railway line, a will originally should not assume by expressway of pressure
“Expressway in the design does not exist.” Transportation planning institute an anonymous experts say, is that the first cause congestion of Inner Mongolia in hebei places of expressway traffic management section of mechanism, fragmented management confusion, Secondly, as the actual freeway traffic management, and highway traffic expressway traffic system of the original information interaction mechanism, The most important is, as the traffic trunk northwest expressway, undertake too much pressure, exposed the freight transportation means that a long and narrow corridor.
The expert says, for the expressway traffic problems, the big unit has begun with Beijing related field trip, they would not rule out three of the establishment linkage mechanism, and open up new freight channel, let more smoothly in Inner Mongolia coal, coal circulation has been put on the agenda.
Beijing transportation research center WenHuiMin deputy chief engineer will be the crux of the congestion of single point freight way. WenHuiMin expressway traffic congestion, said the direct reason, is a large truck occupied highway resources to solve this problem, the most direct and efficient way is to open a, a special railway line, originally should not assume by expressway of pressure. She thinks, railway transport costs far less highway transportation, it also makes up the railway line in May.
But the current, hebei province has really looking for a new channel for expressway traffic congestion in the tram.
On August 26, in zhangjiakou area highway ShuDu bao chang job scheduling conference, hebei bureau deputy commissioner of YangGuoHua says, to speed up the ZhangShi ZhangBaoJie highway construction period, and the source, strive for progress, at the same time, as the effective dovetailing general countries, make the vehicle in the province ZhangShi expressway, can stand on the source, can pass under smooth.
Recently, traffic transportation minister li shenglin on expressway traffic problems on research, in order to promote the construction of a new channel, combining 1025 “, “planning, actively building a scientific and reasonable channel, fundamentally solve the problem. Actively support for Beijing and hebei roads, construction of highway as 25 kilometers of urban-rural benefit readjustment in hebei province, and actively support 110 of 150 kilometers ZhangZhuo as fixed line in a certain extent, so as to ease congestion.
Li shenglin says, considering the political center of Beijing as the particularity of traffic transportation, is preparing to write report to the state council, scientific reasoning, overall consideration, seek a complete solutions.
